This article is the first in a series reviewing unique or updated label requirements for key herbicides. Certain dicamba products were approved for post-emergence control of weeds in Xtend Soybean in 2017. The labels for these products include some additional requirements intended to reduce the potential for non-target injury caused by herbicide drift.
This article is the second in a series reviewing unique or updated label requirements for key herbicides. Paraquat is the active ingredient in the herbicide Gramaxone SL 2.0 and others. When handled carefully, paraquat is an effective weed management tool that would be difficult to replace in terms of effectiveness on hard-to-control species like pigweeds.
This is the third article in the series reviewing unique or updated label requirements for key agronomic herbicides. Keep in mind that instructions printed on the herbicide label supersede this information.

Herbicides that have gained approval for use in agronomic crops in 2020 are discussed in this article, as well as some products that anticipate approval for 2020. Remember to always read and follow label directions.
Growers who decide to terminate their wheat crop because of poor stands or weather-related damage need to consider the persistence of herbicides applied to the wheat. Many wheat herbicides have fairly long crop rotation restrictions.
It is that time of year again for post-emergent applications of Engenia, Fexapan, and Xtendimax on dicamba-resistant soybeans. In light of the recent court ruling, it is vital that application restrictions are followed closely to prevent non-target dicamba injury to conventional, Enlist, and Liberty Link soybeans.
Atrazine is a key herbicide for corn and sorghum production and fallow systems. An interim decision has been recently been released in response to a routine registration review. Read more about how this may affect Kansas farmers in this article.
On October 27, 2020, the EPA issued approval for three labels for over-the-top dicamba application. The labels will be effective until 2025. More details are included in this article.

Don't forget that the 2021 labels for over-the-top applications of herbicides containing dicamba have cut-off dates. For soybeans, this cut-off is just around the corner. Applications to cotton have a few weeks longer. Read more in this short article from Sarah Lancaster.
On January 11, the EPA renewed labels for Enlist One and Enlist Duo for seven years. These are the only 2,4-D formulations approved for over-the-top herbicide application to Enlist E3 soybean and Enlist cotton. The labels come with some additional restrictions compared to the previous labels.
Paraquat is a restricted use herbicide that was first commercialized in the 1960s and is one of the most widely applied herbicides in the United States. This article discusses recent changes made by the EPA in 2021 regarding the proper use of this herbicide.
